This genre, characterized by its catchy melodies and widespread appeal, has evolved over the years, influencing and incorporating elements from various other genres of music.

By the 1970s and 1980s, pop music became synonymous with the likes of Michael Jackson and Madonna, who not only pushed the boundaries of music production but also made use of music videos to enhance their appeal. Michael Jackson’s "Thriller," which includes hits like "Beat It" and "Billie Jean," remains one of the best-selling albums of all time, showcasing the global dominance of pop music.
